Investigao sobre as propriedades e o mecanismo de corte do caule da penia da rvore do leo by Jiaming Liu, Yue Liu, Song Chen Estimated delivery 3-12 business days Format Paperback Condition Brand New Description A colheita mecanizada do fruto da peónia oleaginosa é uma condição importante para a industrialização da peónia oleaginosa. É de grande importância para melhorar a autossuficiência de óleo comestível e resolver a contradição entre a oferta e a procura de óleo comestível. No entanto, a colhedora de frutos de peónia oleaginosa existente só pode satisfazer parcialmente as necessidades de operação mecanizada, mas o mecanismo de corte do caule e os parâmetros da ferramenta de corte ainda carecem de investigação teórica suficiente, e o design ideal da colhedora de frutos não foi realizado. Por isso, este trabalho considerou o caule da peónia oleaginosa como objeto de investigação, e realiza investigação experimental sobre o mecanismo de corte macro, a diferença de microestrutura e as caraterísticas de deformação por corte do caule. Com base nisto, é estabelecida uma equação constitutiva do corte do caule e os parâmetros-chave da ferramenta de corte são optimizados através do método de simulação de elementos finitos, o que fornece uma base teórica e apoio técnico para a conceção da máquina de colheita de frutos de peónia.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
